its aldol imo.
on 4 positions (4 alpha acidic H of the cyclic di ketone)
Got it thnks
3 for both meta directing
Yeah I did 3 with same reasoning as Arush
-m group kyu nitration krega?
In other groups there is still possibility of poly nitration, whereas in 3 it is already much deactivated and due to nitration at the meta, it becomes more, and all places left are Ortho and para wrt -M groups.
Lets wait for ans
Given ans is 3.
NO2+ is strong electrophile so can do nitration on any ring
2 pe para pe hoga as ortho high steric hindrance factor
Why is Ortho hindered here.
Three large groups can't be joined in same order..
Ohk, is OH considered a large group?
Three large groups cannot be join if incoming comes to middle ...
Not for side ways attack
Afaik its just three groups aren't stable at all in same order
